Abstract
The utility model belongs to the technical field of engineering machinery and relates to a fastening device, particularly to a fastening device for a pin shaft, which acts on an overhead working truck and performs anti-rotating limit on the pin shaft connection of the overhead working truck. The device comprises an anti-rotating plate, a locating plate, a pin shaft and a round nut, wherein a transversal elongated slot in vertical symmetry is arranged at one end of the pin shaft and matched with the long hole of the anti-rotating plate; a round hole at the other end of the anti-rotating plate is matched with the locating plate welded on a side plate; and the other end of the pin shaft is a thread and locked by the round nut, thus achieving a fastening purpose.
Description
Technical field
The utility model relates to a kind of securing means, be specifically related to a kind of act on high-altitude operation vehicle and the bearing pin of high-altitude operation vehicle connected carry out the spacing bearing pin securing means of anti-rotation, belong to engineering machinery tool technical field.
Background technique
At present, the bearing pin that high-altitude operation vehicle jib or turntable are connected with oil cylinder uses the axle head baffle plate usually, and baffle plate is welded on the bearing pin; The other end of baffle plate adopts and is bolted on the side plate of arm.Baffle holes and the accurately contraposition of side plate upper screwed hole in installation process cause to be not easy to install; In use, because bolt receives shearing force bigger, after long-term the use, cut off easily, thereby cause bearing pin to rotate, increased the wearing and tearing of bearing pin and jib side plate hinging hole, be easy to generate the gummed phenomenon, thereby influence the normal use of equipment.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of above-mentioned existing technology, a kind of bearing pin securing means is provided, and this device includes torsional stop, positioning plate, bearing pin, round nut; One end of bearing pin has laterally zygomorphic horizontal elongated slot; Cooperate with the torsional stop elongated hole, the other end circular hole of torsional stop cooperates with the positioning plate on being welded on side plate, and the other end of bearing pin is a screw thread; The locking of employing round nut, thus reach fastening purpose.
The technological scheme that the utility model adopts is: a kind of bearing pin securing means; This device is included on the jib side plate and is welded with positioning plate; It is characterized in that: described device also includes bearing pin, torsional stop, and an end of described bearing pin has laterally zygomorphic horizontal elongated slot, and the other end is threaded; One end of torsional stop is an elongated hole, and the other end is a circular hole; Described positioning plate is a cirque structure, and has the crescent moon gap.
The microscler nose end of described torsional stop cooperates with the horizontal elongated slot of bearing pin splaying; Torsional stop circular hole end and positioning plate Spielpassung; Bearing pin symmetric transverse well width up and down is slightly larger than torsional stop thickness, and the bearing pin threaded end is locked with round nut.
Described positioning plate and jib side plate adopt the fixing or screw of welding.
Described positioning plate is cirque structure or is full circle ring, completely circular structure.
The utility model has the advantages that: adopt above structure, torsional stop and positioning plate closely cooperate, and have limited the rotation of bearing pin, thereby effectively prevent the loosening disastrous effect of bringing of bearing pin; Simultaneously, the utlity model has characteristics such as simple in structure, easy to assembly, reliable lock.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model sectional view;
Fig. 3 is the torsional stop structural representation.
1. torsional stops among the figure, 2. bearing pin, 3. positioning plate, 4. round nut, 5 side plates.
Embodiment
As shown in the figure: a kind of bearing pin securing means, this device are included in and are welded with positioning plate 3,3 on the jib side plate 5; Described device also includes bearing pin; 2, torsional stop 1, and an end of described bearing pin 2 has laterally zygomorphic horizontal elongated slot, and the other end is threaded; One end of torsional stop is an elongated hole, and the other end is a circular hole; Described positioning plate is a cirque structure, and has the crescent moon gap.
The microscler nose end of described torsional stop cooperates with the horizontal elongated slot of bearing pin splaying; Torsional stop circular hole end and positioning plate Spielpassung; Bearing pin symmetric transverse well width up and down is slightly larger than torsional stop thickness, and the bearing pin threaded end is locked with round nut.
Described positioning plate and jib side plate adopt the fixing or screw of welding.
Described positioning plate is cirque structure or is full circle ring, completely circular structure.
Working procedure: positioning plate 3 is welded on the jib side plate 5,, is stuck in bearing pin 2 and has symmetrical elongate slots end place, should make big hole aligned plate 3 on the torsional stop 1 in the installation process, and it finally is fastened on the positioning plate 3 then with torsional stop 1 microscler nose end.After the installation, the other end of bearing pin is with round nut 4 lockings.
Claims (4)
